Do You Know About Light And Reflection? Quiz

Diffuse reflection occurs on a dull and/or rough surface. Unlike specula reflection, which occurs on smooth and shiny surfaces, diffuse reflection happens when light rays hit an uneven surface and scatter in different directions. This type of reflection results in a loss of intensity and creates a softer, less focused reflection.

Lambertian Reflectance is a model of diffuse reflection. Diffuse reflection occurs when light is scattered in many different directions upon striking a rough or textured surface. Lambertian Reflectance specifically refers to a surface that reflects light uniformly in all directions, regardless of the angle of incidence. This model is commonly used in computer graphics and computer vision to simulate the behavior of light on different surfaces.

There are two types of light reflection.

Specular reflections form images because they involve the reflection of light rays in a single direction, resulting in a clear and focused image. These reflections occur when light hits a smooth and shiny surface, such as a mirror or a polished metal, and bounces off at the same angle as it arrived. The reflected light rays maintain their coherence and create a distinct image of the object being reflected. On the other hand, diffuse reflections occur when light is scattered in various directions by a rough or textured surface, resulting in a blurred or scattered image.

The reflection on a shiny material is called "specular." Specular reflection refers to the mirror-like reflection of light off a smooth surface, such as a polished metal or glass. It results in a clear and focused reflection, where the angle of incidence equals the angle of reflection. This type of reflection is different from diffuse reflection, which occurs when light is scattered in different directions off a rough or matte surface. Rational and straight line are not terms related to the reflection on shiny materials.

Fibre boundary of an organic material will cause a diffuse reflection because organic materials have irregular surfaces that scatter light in different directions, resulting in a diffuse reflection.

The type of reflection that occurs is determined by the material type. Different materials have different properties that affect how light is reflected off their surfaces. For example, a smooth and polished surface will produce a regular reflection, while a rough surface will produce a diffuse reflection. The material's composition, texture, and surface finish all play a role in determining the type of reflection that occurs.

When light reflects off a material denser than the external medium, it undergoes phase inversion. This means that the light wave undergoes a 180-degree phase shift upon reflection. This occurs because the denser material causes the light wave to slow down, changing its wavelength and phase. As a result, the reflected light wave is flipped in phase compared to the incident light wave.

The correct answer is "The incident ray, the reflected ray and the normal to the reflection surface at the point of the incidence lie in the same plane." This statement is not a law of reflection because it does not accurately describe the behavior of light during reflection. The law of reflection states that the incident ray, the reflected ray, and the normal to the surface of reflection all lie in the same plane.

Diffuse reflection enables us to see objects. When light hits a rough or uneven surface, it scatters in different directions, allowing us to perceive the object. This type of reflection occurs when the surface is not smooth enough to reflect light in a single direction, resulting in a blurred or scattered reflection. Specular reflection, on the other hand, occurs when light reflects off a smooth surface, like a mirror, creating a clear and focused reflection. Straight line and rational are not types of reflection and do not relate to the ability to see objects.
